Question about Garmin nuvi 350 GPS Receiver
Having taken several Nuvi's apart, the flip up antenna has a 1/4" wide flat flex cable that runs from the flip up antenna assembly to the main board.
The flex cable carries the voltages required to power the antenna assembly and bring the signals back to the main board.
There is actually a printed circuit board in the flip up antenna assembly. It's possible that this is the receiver itself.
The flex cable runs through the round center hinge of the antenna assembly on the right (looking at the Nuvi from the rear) back to the main board.
There is also a magnet involved with the flip up antenna assembly that tells the main board whether the antenna is up or down. If the antenna is down, the Nuvi will NOT look for satellites.
A couple things can happen here that can make your Nuvi not find satellites: Assuming you have tried a hard & soft reset:
1. The antenna flex ribbon cable has become damaged.
2. The antenna flex ribbon cable has become detached from either end (it's held in with just a snap down flap).
3. The magetic switch isn't operating correctly and the main board thinks the antenna is down.
4. The front-end receiver has failed.
If your good at taking things apart (and the Nuvi is a little tricky to take apart), you might be able to verify some of the possibilities I mentioned above.
You might also try looking for a Nuvi for parts on eBay. Maybe you can find one that has a bad LCD screen and salvage the antenna from it.

Same here. I had mine for 13 months. Tried hard reset, cleared and reinstalled all data and nothing.
I called Garmin, it took a half hour before a person got on the phone. They gave me instructions to ship it back to them and said they would send me a refurbished unit even though it's a few weeks outside warranty.
There are many posts about this problem on this website. Probably why they are not making the flip up antenna on the newer units.
I know it sucks that you paid all that money and it doesn't work. I bought a magellan maestro while my GPS is getting repaired and I already took it back.. Garmin is way better than the magellan.
